As my past watch choices have shown, I like simple black and white watches albeit pieces that often come with hefty price tags. The latest is from Patek Philippe, of which no watch collection would be complete without. Patek Philippe & Co. has gained over 70 patents since it's 1851 inception and dominates luxury auctions worldwide with record-breaking bids. Unlike the multi-million dollar timepieces that show up at Sotheby's and Christie's, the Calatrava “Clous de Paris” (Ref. 5116G) can be found for less than $20,000 and is an absolutely beautiful wristwatch that would complement any outfit, if not take center stage. For those who have never noticed, timepieces using roman numerals usually use IIII in lieu of IV, and while no unanimous reason exists, there are multiple theories listed here. For more timepieces, look at A. Lange & Söhne's Lange 31 and Cartier's Tank Francaise.
